　　【CC1101】

　　低功耗(低于 1GHz)射频收发器

　　描述

　　CC1101 is a low-cost sub-1 GHz transceiver designed for very low-power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315, 433, 868, and 915 MHz, but can easily be programmed for operation at other frequencies in the 300-348 MHz, 387-464 MHz and 779-928 MHz bands.

　　The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 600 kbps.

　　CC1101 provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-on-radio.

　　The main operating parameters and the 64- byte transmit/receive FIFOs of CC1101 can be controlled via an SPI interface. In a typical system, the CC1101 will be used together with a microcontroller and a few additional passive components.

　　The CC1190 850-950 MHz range extender [21] can be used with CC1101 in long range applications for improved sensitivity and higher output power.

　　Reduced Battery Current using TPS62730

　　The TPS62730 [26] is a step down converter with bypass mode for

　　ultra low power wireless applications

　　In RX, the current drawn from a 3.6 V battery is typically less than

　　11 mA when TPS62730 output voltage is 2.1 V. When connecting CC1101

　　directly to a 3.6 V battery the current drawn is typically 17 mA

　　In TX, at maximum output power (+12 dBm), the current drawn from a

　　3.6 V battery is typically 22 mA when TPS62730 output voltage is 2.1 V.

　　When connecting CC1101 directly to a 3.6 V battery the current drawn is

　　typically 34 mA

　　When CC1101 enters SLEEP mode, the TPS62730 can be put

　　in bypass mode for very low power down current

　　The typical TPS62730 current consumption is 30 nA in bypass mode.

　　The CC1101 is connected to the battery via an integrated 2.1 Ω (typical)

　　switch in bypass mode
